My IP90 does not respond to new color ink cartrige. It tells me to install new cartrige but does not recognize that the new cartrige has been installed. I have tried several cartiges with no luck.

That printer has a little switch on the carriage assembly that is made when the ink is put in. It's a tiny switch easily broken, and you have to replace the carriage assembly if it's broken. Make sure you place the ink in properly, the right side goes in under the ledge and then press down the left side.

Take to a ink refill store and ask the to test on there machine(cartridge world etc) it will tell if cartridge is good or not! hope this helps!!!

According to Canon, the if several actions did not correct the issue, it was a hardware problem. They sent me the location of the closest repair shop. I spoke to them and to do the repair is $80 + parts which my research estimated at between $50-$80, for a total cost of $130-$160 plus 10% cook county Illinois sales tax. I have ordered a new updated printer for a total of $215 plus no tax or shipping charge. I'll be taking the old printer to a location for recycling. I can't believe how disposable this equipment has become. What a waste of raw materials and energy.

try to unplug your printer while it is in ON state ...it reset all your settings and after that it can recognizes your full cartridges..

Remove the printer from control panel, under installed printers, then unplug the usb cable and reinstall the printer drivers using printer cd, or download from canon support website.

I had this problem recently with my IP90. Both the black and color heads were clogged. After running the "canned" routines several times to clean the heads and deep clean the heads...still didn't help...here's what I did:

1. open the top lid to have the cartridges that are inserted in the print head move to the middle of the printer.
2. remove both cartridges
3. What is left there is the print head holder. Slightly move it to the right and gently lift the print head lock.
4. Grasp the print head and lift it out of the tank.
5. Have several paper towels hand and know that you will have color and bw ink on your fingers
6. Put the print head on the paper towel
7. Pour rubbing alcohol on the blk and color heads and let them sit of about 10-15 minutes.
8. after that dry the heads and re-insert them in the printer
9. I put new cartridges in the printer and ran clean and deep clean a few times.
10. My color and black and white print came right back!

Hope this helps.

uninstall the software and reload it it will mostly fix your problem.
if still the problem presists .
feel free for further assistance.
thanks

can anyone tell me what to do

What is the model of your printer? Try replacing the ink cartrige coz maybe the black cartrige is already empty

Have you performed a nozzle test? If one or more of the colors is missing when you do the nozzle test, the printhead itself is likely in need of replacement.

Before considering replacment, perform a clean on the printer. Due to variations between mac and pc, please see your documentation / support files on how to perform the clean on your printer.

After performing the clean, again perform the nozzle check to see if the problem is resolved.

If still not resolved, remove and re-install any cartridges you recently replaced to make certain they are installed correctly.
